NATO is a collective defence organization, a community of interest, and, as I say, a political-military organization. We tend to focus on those skeptics who say there's no military threat, so why do you need a NATO? Well, it belies or ignores the importance of the dialogue on the consultation that happens on a range of issues, from cyber-security to how you deal with weapons of mass destruction.
This is a community of values and interests, as well as a military alliance. Frankly, at the end of the day, it is a military alliance, too, and when something like 9/11 happens, it enables us to work together with our closest like-minded partners in defence of our common values and interests.
